A very variable plant. The leaves of young plants are often remarkably toothed.
Mr. Miers indicates four species, bat he assigns no characters. We find the form
and clothing of the leaves to vary so much, even on the same specimens,, .that we are
folly persuaded that all the forms hitherto known belong to one species.

This genus and the last agree with Aspidocarya iu the subterminal position of the
style in the drape, but differ from it in the decidedly amphitropous ovules and pel-
tate seeds. In Tinospora the internal process of the putamen is much more deve-
loped than in Pardbana,. in which it is merely a depression on the surface of the
putamen, convex internally. Here (as in Anamirta and Coscinium] the condyloid
process has a narrow base, and projects far into the interior of the cell, and is em-
braced by the overlapping edges of the seed. It is also hollow, and the iuterior is
occupied by a gelatinous mass. The cavity of its interior communicates with the
exterior of the putamen by two perforations in the latter, one on each side of the
median line. These do not, as in Anamirta and Cosdmum, form elongated canals
in the thickened bony mass, but the structure is the same as in those genera, differ-
ing only in degree. The albumen on the ventral side of the seed is divided into
irregular masses by thin transverse plates of cellular tissue, which penetrate almost
to the embryo.
All the species of this genus are remarkable for their extreme vitality. When the
main trunk is cut across or broken, a rootlet is speedily sent down from above, which
continues to grow till it reaches the ground, and restores the connection.
• Gha&mawth&ra* of Hochstettcr, with the habit and inflorescence of Tinosjtora, has
rnonadelphous stamens. The fruit is also u little different, the concavity of whajt we
have, <*alled the podosperm forming a deep hollow on the ventral face of the putamcu,
conspicuous externally as soou as the sorcocorp is removed, almost as iu (.\tlyvo~
of Nultall, figured in Asa Gray's goacra of North American plants. The
